A number of serious studies have been conducted to decipher relationships between geological environment, potable/drinking water, and diseases as they were considered to have triggered suffering due to diseases among people. Chronic anemia can be caused by prolonged exposure to drinking water contaminated with cadmium (Cd). Under such circumstances, accumulation of Cd is manifested in the kidney, resulting in cancer and cardiovascular diseases. The aim of this study is to present the impact of Cd-contaminated drinking water on human health among the residents of villages in Winder. Collection of about 48 groundwater samples at an average distance of 1 to 2 km between the sampling sites has enabled a sufficient geological representation of distribution of minerals and elements in the samples. Concentration and comparison of Cd in the study area sample sites reveal highest values (24.2-30.0 ppb) in the northeastern and southeastern sectors, covering parts of all three geological areas of Bela Ophiolite of Cretaceous age. Conducted questionnaire surveys provided relevance between cause and effect nature of Cd bearing diseases among which kidney, joint, and night blindness are more prominent. Due to this phenomena, toxic risk of Cd in drinking water was high as per calculated health hazard indices. The use of this water by the villagers may cause health problems and disorders among the inhabitants of the area.
